# Generate Synthetic Tests From Session Replay

## Overview{% #overview %}

[Real User Monitoring (RUM)](https://docs.datadoghq.com/real_user_monitoring.md) gives you end-to-end visibility into the real-time activity and experience of individual users. [Synthetic browser tests](https://docs.datadoghq.com/synthetics/browser_tests.md) allow you to observe how your systems and applications are performing using simulated requests and actions from around the globe.

You can trigger a [Bits Testing](https://docs.datadoghq.com/synthetics/bits_testing.md) job to generate tests based on a session replay's summary.

## Generate a test from a session replay{% #generate-a-test-from-a-session-replay %}

In the [RUM Explorer](https://app.datadoghq.com/rum/sessions), filter for sessions with [Session Replay](https://docs.datadoghq.com/session_replay.md) available, then open one with a Session Summary in its details panel. Click Generate a Test With Bits Testing.

Bits Testing pre-fills the job's starting URL and goal from the session.

Review the prefilled job, adjust its [location, profile, and review mode](https://docs.datadoghq.com/synthetics/bits_testing.md#trigger-a-bits-testing-job), and click Start Discovery.
